I have a 93 K1500 with the 350 and the 5 speed manual transmission. starting last fall the speedometer would randomly drop to 0 and if on cruise it would cut out not too long after i noticed that the odometer would also stop reading when the speedometer stopped working. fast forward to now where the Speedo only works on occasion mostly on right turns and the odometer only registers 1/3 of gps mileage on average. the shift indicator is also out of whack. i have replaced both the vss and the vssb to no avail so i turn to you for help. My electronics background is telling me is a bad ground but i haven't been able to find any as of yet.
I know that sometimes other seemingly unrelated issues are in fact related so the others that i have are: park brake light is almost always on, the temp gauge hasn't worked in the time I've owned the truck, the drivers side door doesn't turn on the cab light when opened (passenger door does).
